An insult to use when somebody is being a retard, it can be used in various different forms - preferably the most complicated. It makes the insult funnier if the victim doesn't know what you're on about. Which you most likely won't - because you are all tupes, who don't own awesome home-made certificates.
*Originated from the mistake of spelling 'type', 'tupe'. Well done ;]
Cooldude: You're such an unexciting, low caffine, tea-less tupe...
Retard: What the hell is a tupe?
CoolDude: Ha! You're such a super-tupe! You don't know what tupe means!
